Mein gott. Had for a long time repressed that me myself once upon a time went to a ninja-school. By the way I think that their sparring looked like grecco-roman wrestling( not very good I would say). Nevertheless why do not they skip the ninjery and go direct to wrestling. Regarding it also being designed for warfare once up on a time. Doubt that mediveal japanese warriors trained like the modern day bujjinkan-ninjas generally do. Rather I think it is more likely that their hand-to-hand combat looked more like grecco roman. If they would miss the relgious stuff in wrestling-training. They could start a intrest in roman mythology. Maybe scream "Hail Mars" at the beginning of their training-sessions

Pretty sure it's this guy. Same "training since 1972" matches statements in this thread.

"Lineage stretches back 2000 years". Oh, boy

I wonder how many of those koryu jujutsu/bugei lineages he has any sort of teaching license in? Regular laundry list of complex arts it would take at least 10 years to get menkyo in, let alone all of them.
